Anti-Spam SMTP Proxy

The Anti-Spam SMTP Proxy (ASSP) Server project aims to create an open source platform independent SMTP Proxy server which implements whitelists, Bayesian, and virus filtering to help stop unsolicited commercial email (UCE). Anti-spam tools should be adaptive to new spam and customized for each sites email patterns. This easy to use tool works with any mail transport and achieves these goals requiring no operator intervention after the initial setup phase.

            Release Notes: This release contains a number of bugfixes, specifically with regard to RunAsUser, chroot, move2num, and the Analyze admin page.

There are also minor enhancements to improve spam detection, specifically in the way mail is pre-processed.
